BBQ fish recipes

Looking for a nice recipe for some BBQ fish. I'm not too fussed on the fish so long as I can get it in my local fish mongers (it isn't a huge one) in Aberystwyth, I quite like meaty fish so that could be a bonus! Looking to feed 5 adults so include portion size please.

The best fish for barbying, from recent experience feeding my veggie friends, is Hake. It's meaty and stays together nicely. You don't need to do much with it, wrap it in foil, plenty of freshly squeezed lemon, and season with some black pepper, and Bob's your aunties live-in-lover! It's really nice! I even opted for it over a second (or was it third?) Burger!

Mackerel barbies well too. Fresh and simple. It's got plenty of oil to keep it moist.

For a "meaty " recipe, try marinading some tuna steaks in a jerk seasoning.
Allspice, thyme, pepper , paprika, salt ( or a chicken stock cube), cumin, oil, touch of vinegar or lemon juice. And a bit of chilli powder depending on taste.
Couple of hours in the marinade before the barby. Drizzle what's left of the marinade over half way through cooking.

Aah.. North Portuguese coast in the 80s.. A claxon sounding in the village when the menfolk get home from fishing.. A flurry of activity followed half an hour later by the smell of barbequed sardines as everyone in the village fires up in the street outside the front of their houses

A nice way to cook fish on the BBQ is to do it on a plank of cedar. Soak the plank in water for a few hours. Light the BBQ with the coals on one side, and pop plank on the other side so the heat is not directly under the plank. Wait for it all to get nice and hot with the lid on the BBQ. Pop the fish on the plank to cook for as long as it needs depending on the fish size and type with the BBQ lid on.
We did this on a webber with some filets of salmon and it was very nice, very moist.
